> When trying to add error logging to a transacted pipeline, I discovered the following
issues:
> (1) onException/onCompletion do not work in a transacted route
> (2) if the transacted tag is not the first element in the route, all the endpoints above
it will be silently ignored
> (3) custom error handlers interact very awkwardly with transacted routes (specifically,
a non-transacted error handler will not work at all on a transacted route)
> I was able to solve my problem using doTry/doCatch; this may be a good candidate for
adding to the docs.
> I suggest that, if the above issues are not corrected (especially 2+3, which may not
be route designs that it is desired to support), they should trigger errors in the corresponding
pipeline.
> I have attached a tgz of examples showing problems (1) and (2) above, as well as my successful
route.
